discharge

so i’ve been dealing with this discharge for a few months and can’t seem to get rid of it even tho i have very good hygiene and take care of my body. it has a smell and makes me so self conscious about myself and having sex. there’s no other symptoms except for the smell and that it has a yellow tint to it. (no itching etc) i have no insurance but i can go to this clinic that is reasonably cheaper and get tested for every std for around $100 or is it more likely that i have BV and ask for antibiotics for that ?
